With reference from @redent84, find the code logic.

override func viewWillAppear(_ animated: Bool)

{
    super.viewWillAppear(animated)

    scrollView.contentSize = CGSize(width: scrollView.frame.width * CGFloat(imagesArray.count), height: scrollView.frame.height)

    scrollView.isPagingEnabled = true

    //        imagesArray.insert(imagesArray.last as? UIImage, at: 0)
    //        imagesArray.insert(imagesArray.first as? UIImage, at: imagesArray.count - 1)


    var testArr = ["A", "B", "C", "D"]

    let firstItem = testArr.first
    let lastItem = testArr.last

    testArr.insert(lastItem as! String, at: 0)
    testArr.append(firstItem as! String)
    print(testArr)


    for i in 0..
